I have a different strain response from HMA layer under different vehicle speeds, I know the changes in response due to the viscoelasticity behavior of HMA layer. I have the Master curve but how I can get the exact modulus works for a specific speed.

Dear Muath
The duration of load depends on the vehicle speed (s ) and the tire contact radius (a) .
A reasonable assumption is that the load has practically no effect when it is at a distance of 6a from the point, or
d = 12a/s
If a = 6 in . and s = 40 mph (64 km/h) = 58 .7 ft/s (17.9 m/s), d = 0.1 s .
